TADF in solid hosts

What is it about?

Thermally activated delayed fluorescence (TADF) emitters are the latest advance in seeking to achieve 100% internal quantum yield and even beat the dominant phosphorescent materials in commercial OLED devices. Though mostly having a rather simple structure, donor–acceptor-based TADF compounds demonstrate rather unexpected emission features solely in solid hosts, namely, temporal dynamics of emission spectra and prolonged delayed fluorescence lifetime. This article presents an overview of different approaches for analyzing the untypical solid-state TADF dynamics, its implications in unexpected emission phenomena, as well as methods to mitigate its negative impact.
